[PATCH] Find size of SHA1 object without inflating everything.
This adds sha1_file_size() helper function and uses it in the rename/copy similarity estimator. The helper function handles deltified object as well. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
